Is RGP lens care solution expensive? How long can a bottle last?

We sell a bottle of 95, 120ML, Dr. Dunxinjie. Normal use should be 1 month, because RGP's nursing solution is mainly suitable for storing lenses, and it needs to be washed off with normal saline when it is taken out of the maintenance box, so it is not as expensive as soft lenses, but it is really expensive to maintain!

If used normally, RGP is almost not long! You can consult a hospital specializing in this kind of service, such as Peking University Optical Center (the first hospital in China to carry out contact lens fitting led by a full-time ophthalmologist).
